Cyrilic Cypher Multi

This is the multiplayer version, solo version here has more thwarts and less damage.
This deck is justice but it does not thwart that much. I usually play it with an other justice player.

Steel Fist Artist

Your goal is to change form every turn to shuffle Steel Fist with your alter-ego response or Mutant Education.
Most Colossus decks do not need X-Gene. But this one does! You virtually draw tons of copies of Steel Fist before your deck is empty. Add Deft Focus and you can play Steel Fist for free.

Colossus Confucius

Your main goal for turn 1 is to confuse the villain. Before Psylock's pack this was a gamble, either you get Steel Fist or you have to spend 3 ressources for Concussive Blowor Sonic Rifle.
That's way too expensive! is so much better. This new card along with Dazzler and Professor Xwill make sure you get that confuse turn 1.
PlayFloat Like a Butterfly for you and your pals to boost everyone's damage!

3 Draw engines

Iron Will, Moira MacTaggertand Cypherare your draw engines. They are your top priority. You might be surprised butOrganic Steel and Armor Up are very low priority. Don't hesitate to use them as ressources to play the draw engines. You will get them back soon enough. Since you change form every turn, the best engines are Iron Willand Moira MacTaggert.
Cypher is a bit tricky cause he requires a lot of set up. You need to give him Honorary X-Men and to to heal him every turn with Avengers Mansion. Why so much trouble ? Colossus does not have access to piercing in justice. Cypher will help you removing those though cards. And once you are set up, he draws you a card every turn and he deals 2 damages with Float Like a Butterfly.

Thwarting ?

This deck is mostly focused on confusing and damaging, but your allies are a good source of thwarting (except for Cypher, he wants to attack every turn). Make sure an other player at the table is a thwart specialist.

Cooperation

An other player dealing with threats is pretty much compulsory! You have expensive X-men allies so a leadership player could give you Uncanny X-Men. Playing Call for Backup will help you get Cypher more consistently. You will mostly exhaust for your basic attack that gets better with Float Like a Butterfly, the agression player could add some more damages to you and Cypher with some classic upgrades and support.
Finally you can very well ask other players to play Build Support, Superpower Training and Honorary X-Men if you are a maniac about having a 40 cards deck.
